SAFETY DEVICE.

- Application filed June 18,1925/ Serial No. 38,097-

To all whom it may concern:

"Be itfknown thatI, PHILIPH. DAUB, a citizen of theUnited States,residing at Helena, in the county of Sandusky and State of Ohio, haveinvented certain new and'useful Improvements in Safety Devices, of whichthe following is a specification.

1 This invention relates to mechanical devices for operating a safetygate or signal or signal lights and the like.

An object of this invention is to provide will autotlirection, operate arailway. safety device or gate or signal or signal lights or any kind ofsignal or gates at railroad crossings, or where main market or otherroads cross the railroads, and which will be inoperative when'the trainis moving in the opposite direction.

It is a further object this invention to provide a device on the outsideof the rail and to provide adevice in which a broken flange or" anyimperfection will not interfere withthe operation of the device orinjure the train by contacting the de ,vioe. r A further object of thisinvention is to provide a device of this character which is positive inoperation, which is of simple fcons'truction, which is easily andquickly in- .stalled, and which may be installed Without any change inthe rail structure, and which maybe manufactured at a minimum cost.

With the foregolng and other ob ects in view, I-have lnvented the deviceshown 1n the accompanying drawings, in which:

Figure 1 is a top plan view of a rail road provided withmydevice.

Figure 2is a side elevation in normal condition. 3

Figure 2 is a like view to Figure 2 showing the operation upon a carwheel passing in one direction.

Figure 3 is a top plan view of the base plate.

Figure 4: is a side elevation of the link buffer separated.

Figure 5 is a top plan view of the show ing in Figure 4. 4

Figure 6 is a detail.

Like reference characters indicate like parts throughout the severalviews and in the specification in which there is provided a base plate 2adapted to be inserted bepulley 15 and suitably spaced upon the ties ofthe track are pulleys 16. Passing over the pulleys 16 and partiallyaround the pulley 15 and artially around the pulley 12 is a cable 17,the cable 17 being connected with an adjustable eye-bolt 18 mounted in atie 19. In assembling, the cable 17 is suitably adjusted by means ofthebolt 18, sothat, by a predetermined pressure the device normallyrests as in Figure 2.- Thatis to say, thejoinedpOr tions of the links 6and 7 areslightly-up standing above the surface of the rail 3. Upon thepassage of a train to the right, as shown in Figure 2 the wheel 20 ofthe car contacts the link 6, and by reason of the angularity of thepositioning ofthe members 6 and 7, pushes against the memher 7 to slideupon the roller 1 and push against the pulley 12, causing a tighteningof the cable l7' and the actuation of any suitable signalling orgate-closing or other safety device, the cable 17..being suitablyconnectedwith any desired safetyvdevice or appliance, or witha means foractuating such a device from-a remote-position. If

the train should be passing toward the left, as shown in Figure 2, thenthe Wheel 20 would contact the'link 7, which Wouldpush against the link'6 and against the spring 14: and wouldrhave no action upon the-cablethe support is carried by the shoe or plate 2. Furthermore, by thisstructure, a breakage of the flange of the car wheel will in no mannermilitate against the operation of the device, nor will the contact witha broken part of a flange endanger the operation of the train.

It is obvious that the above device may be placed at suitable placesalong the railway and in reverse relation to each other, as, forinstance, one upon each side of a cross road bed, one of these twoWorking in a reverse direction to that of the other, so that upon thepassage of the train in one direction, one of the devices is operated tocontrol the safety device, whereas upon the passage of a train in thereverse direction, the other isoperated to control the safety device.

It is further obvious that this device, being purely mechanical in itsoperation and of simplified construction, dispenses with complicateddevices such as hydraulic, water power, and the like. It is furtherobvious I that by this cable means, the device can be operated at aconsiderable distance from the signal or gate and that the cable can berun a' great distance-so that the device can be fastened on the rail agreat distance from the road crossings.

It is'further obvious that when used with counter-balance gates, thelength of the links 6 and? may be such that no further control meansneed be had, in that the gate can be held entirely open by this deviceuntil the full train has passed over, which cannot be had with the usualtrip devices.

Claims.-

1. A safety attachment eluding slidably mounted ramps, a cable connectedwith one of the ramps, and means for mounting the ramps to move thecable in a single direction. In. combination with a railway rail, a

pair of bar-like members provided with longitudinal slots pivotallymounted rela- "tive to each other, means adapted to engage the slots, aspring mounted at the terminal of one of the bar-like members, andcontrolling means adapted to be actuated bythe other bar-like, member.

3. In a railway safety device, a member adapted to be mounted at theside of a rail, the member including a pair of articulated wheel ramps,the ramps slidably:

mounted, a spring engaging one of the ramp for a railway, in

' pair of members each held at an acute angle relative to ,the rail, themembers pivoted together, aspring at the terminal of one of the members,a pulley carried by the terminal of the other member, and. meansadaptedto cooperate with the pulley for operating a safety device.

6. In combination, a ed to be carried by the side of the rail and to becont-acted .by a wheel passing over the rail, a pulley carried by one ofthemeinbers, a cable andmeans for affixing the cable to a tie, thepulley adapted to movingly engage the cable. I

7. In combination in a railway safety device, a cable, means toradjustably fixing the cable to a tie, pulleys associated with the flexedmember adaptrailway and a member in the'path of a car slidably mountedto the plate member, the

link members in the path of a wheel passing over the rail, andmeans-interconnected with the link members for actuating a safetydevice. I

9. In combination, a flexed member provided with longitudinal slots, aportion of the flexed member in the path of a wheel passing over therail, means interconnected with the flexed member for operating a safetydevice upon a predetermined contact of the wheel and flanged rollermembers mounted within the slots. v

In testimony whereof I afiix' my signature.
